Risk factors for breast cancer:
Gender: Breast cancer is about 100 times more common in women than in men.
Age: The chance of getting breast cancer goes up as a woman gets older.
Genetic risk factors:
Family history:
Personal history of breast cancer: A woman with cancer in one breast has a greater chance of getting a new cancer.
Race: Overall, white women are slightly more likely to get breast cancer than African-American women. African-American women, though, are more likely to die of breast cancer. Asian, Hispanic, and Native-American women have a lower risk of getting and dying from breast cancer.
Dense breast tissue:
Certain benign (not cancer) breast problems:
Lobular carcinoma in situ:
Menstrual periods:
Breast radiation early in life:
Treatment with DES:
Not having children or having them later in life:
Certain kinds of birth control:
Using hormone therapy after menopause:
Not breastfeeding:
Alcohol:
Being overweight or obese:
Tobacco smoke:
Night work:
Antiperspirants
Bras
INDUCED ABORTIONS
Breast implants: These may be linked to a rare type of lymphoma, though
Chemicals:

Being alive increases one's risk of cancer but I am no more considering "curing" that by dying than by changing gender! Not I can reduce the likelihood of breast cancer by 100 time if I go for the sex change. That there may be some increase in cancer rates is statistically (and in terms of actual health) insignificant.

This same site also gives the results on actual research. While there are some minor studies that appear to show some increase - these are from the past and have serious problems with methodology. All the large scale modern studies from places like Sweden show no link. So we can safely say that the accepted scientific position is that there is no significant link

On getting fake emails from atheists: I sincerely hope that this is not the case. If it, the people involved should be ashamed of themselves. BUT atheists are neither more nor less likely to be ethical than any religious group. I think there is good empirical evidence that being Christian doesn't in itself make one good. Try Darley, J. M., and Batson, C.D., "From Jerusalem to Jericho": A study of Situational and Dispositional Variables in Helping Behavior". JPSP, 1973, 27, 100-108.

Onthebeach, well said!
You are far more patient with this rubbish article than me.
I don't care what religious views people hold, as long as it doesn't try to interfere with scientific and medical issues in order to try and prove their views.....

The irony is that the conduct of abortions -- namely the killing of the unborn -- supposedly constitutes womens' health service. Illogically, such killing is regarded as ethical by the pro-abortionists.

I see a raw nerve being touched with the feminist every time they are challenged to take a little responsibility. They scream equal rights and are not even prepared to nuture the babies they carry. No wonder they attack the messenger so vicously.

>> could be seen as ethical, if the purpose was to sabotage an organisation that does serious harm to the wider community <<

Truly, but supporting traditional families as pillars of society (that the World Congress of Families and “Life, Family and Freedom” are apparently about) would not be seen by anybody - theist or atheist, rightist or leftist - as “doing a serious harm to society” just a couple of decades ago.

It is probably true that the majority of those who are against freely available abortions are religious, but there are also many non-religious people who consider making late-term abortions freely available to any woman as doing “serious harm to society”. You do not have to be religious to see the demographic impact of this e.g. in Europe, although views differ on to what extent was this necessary.

>>I don't care what religious views people hold, as long as it doesn't try to interfere with scientific and medical issues in order to try and prove their views.....<<

Exactly my sentiments, Suseonline, when atheist scientists let their delusions about (a non-existent) God interfere with how they explain science to non-specialists in order to “try and prove their views".
